SECTION BEAM.

a noaucn filed January 1a, 1921. semi no. 438,112. 3

To all whom it may concern:

' Be it known that I, RAY THORNTON, a citizen of the United States, and a resident of New Bedford, in the county of'Bristol 5 and State of Massachusetts, have invented a a new and useful Improvement in Section Beams, of, which the following is a specification.

My invention relates to section-beams,

1 and more particularly to section-beams of the type shown in my prior Letters Patent lid-1,239,744 dated September 11, 1917, and

No. 1,297,751 dated March 18, 1919.

' A section-beam is a large bobbin designed to hold about four hundred pounds of war or filling yarn for shipment, and is provi ed with a fixed longitudinal shaft arranged to be mounted for rotation when the yarn is unwound for transfer to a loom-beam or when the section-beam itself 'is used as a loom-beam.

Heretofore section-beam shafts were permanently secured thereto and shipped therewith, and experience has shown that the protfi jecting ends of the shaft become bent or otherwise deformed in transit. This results in an uneven rotation of the section-beam when the yarn is being unwound therefrom for transfer to the loom-beam and in -an 3 irregular winding of the yarn onthe latter,

and when a section-beam is used as a loombeam as is sometimes done especially in weaving fabrics for automobile tires, the uneven movement of the beam, known as as jumping ahead, causes bad spots in the cloth.

The object of my invention is to. rovide a section-beam having a shaft which can readily be removed therefrom before shipet ment and which, being retained in the weaving mill, is not subjected to distortion of its shape by the rough usage whicha-shaft permanently afiixed to the section-beam of the prior art always receives in transit. e By means of my invention not only are the foregoing difiiculties overcome, but also a further advantage is'obtained in that the section-beam can be loaded vertically on the trucks and freight cars thus economizing space and eliminating the necessity for the padding that must be placed around the fpllll beams when they areloaded horizon- With the foregoing object in view my invention comprises asection-beam preferably having cross-banded wooden heads such as described in my prior atents provided with a removable shaft and means, such as rods extending through the barrel, independent of the shaft for clamping the heads to "the.

barrel. A convenient means" for removably securing the shaft to the barrel and at the same time centering the same consists in a.

metallic pipe arranged axially of the barrel on which are mounted the usual disks which support the barrel slats, and bushings having threaded engagement with the shaft near the ends thereof and arranged to accurately fit into the ends of said pipe.

My invention will be described by reference to the drawings which accompany and form a part of this s ecification, and which illustrate'one form 0 shaftless section-beam that has given good results in practice.

In the drawings Figure 1 is a longitudinal section of: a 'section bea'm embodying my mventlon;

Fig. 2 is an end View; Fig. 3 is a transverse section taken on. the line 33 of Fig. 1; and

Fig. 4 is a plan view of theremovable shaft and the bushings threaded thereto near the ends thereof.

In the particular drawings selected for more fully disclosing my invention, 10 rep resents the barrel made up as usual of a dependent of the shaft may be employed for clampin the heads to the barrel as distinguished rom section-beams of the prior art in which this function 18 dperformed by nuts threaded to the shaft an co-operating with the outer faces of the heads, I prefer to employ rods 17 herein shown as four in numberwhich pass through the barrel and heads, and to the end of which nuts 18 are threaded, the outer faces of the heads being countersunk to receive said nuts so that the latter will be flush with said outer faces. Inasmuch as the ends of the pipe 13 and the nuts 18 are flush with the outer faces' 12 to the pipe 13 consists as shown of the flanges 19 secured to said disks by the screws 20- or in any other suitable manner and attached to said pipe by the setscrews 21.

Inasmuch as the usual metallic pipes of commerce are not of absolutely internal diameter, I prefer to employ ashaft 22 of smaller diameter than the bore of the pipe 13 and to provide means for performing the double function of accurately centering said shaft with respect to the section-beam and of detachably securing the same to the structure.

In the particular instance illustrated in the drawings, I show bushings 23, 23 threaded to the shaft near the ends thereof and accurately fitted into the ends of the pipe for which purpose the bore of the pipe will be accurately machined a short distance from the ends thereof. The bushings 23, 23 are each provided with a polyangular flange 24 the inner face of whlcli rests against the outer face of one of the heads, and which are arranged for receiving a wrench, so that when the bushings arev forced along the screw-threaded portions of the shaft toward each other, the said flanges will take against the heads and thereby hold the shaft firmly 1n osition.

- referably the heads are provided with the metallic rims 25 which are grooved to receive the restraining cord employed when the thread is unwound.

ving thus described an illustrative improvement of my invention without however limiting the same thereto, what I claim and desire to secure by Letters Patent is,-

1. A section-beam comprising a barrel, heads for the same, the outer surfaces of said heads being plane, a removable shaft for said barrel, the ends of said shaft extendin beyond said heads, and means indcpen ent of said shaft for clamping said heads to said barrel, the said means not extending beyond the plane of the outer face of said heads and the said section-beam whenassembled with the shaft removed having smooth outer ends.

2. A section-beam comprisin barrel, heads for the same, a. pipe running through said barrel, the ends of said pipe being flush with the outer faces of said heads, a removable shaft in said pipe, the ends of said shall extending beyond the ends of said pipe,

means threaded to said shaft. for centering said shaft with respect tosuid pipe, and means independent of said shaft for clamping said heads to said barrel.

3. A section-beam comprising a barrel. heads for the same, a )ipe running through said barrel, the ends of said pipe being flush with the outer faces of said heads, a removab-le shaft in said pipe, the ends of said shaft extending beyond the ends of said pipe, bushings threaded to said shaft near the ends thereof and fitting into the ends of said pipe, and means independent of said shaft for clamping said heads to said burn-ll 4. A section-beam comprising a barreL.

heads for the same, a pipe running through said barrel, a removable shaft in said pipe,

the ends of said shaft extending beyond the ends of said pipe, bushings threaded to said shaft near the ends thereof. and fitting into the ends of said pipe, and rods passing through said barrel and clamping said heads against the ends of the same.

In testimony whereof, I have hereunto subscribed my name this l i-th day of Jan.

RAY THORNTON.
